Application filed March 2,1, 1912. Serial No. 685,212.

ZIO all whom 'it may poncem B it known that I, SIMON FRIEDBERGR,apcitizenof the' United States,.vresid ing at Philadelhia, county ofPhiladelphia, vand ennsylvania, have invented a new. and usefulImprovement inKnitted Fabrics, of which the following is a full, clear,andl exact description, reference' being had to the' accompanyingdrawings, which form a part of this speoication. l f The object of myinvention is to-produce a fabric adapted especially for use in makinglaundry bags and analogous knitted articles. Insuch articles it ishighly desir able that the fabric of which it is composed 'shall notunravel as a -result of the rough handling to which it is exposed. It isalso desirable that the fabric Yshall be of such elasticity that when.exposed to pulling stresses in different directions, it will give .indifferentdirec'tions to a substantially uniform extent. J

In the drawings: Figure l isa plan view of the fabric as it appears tothe eye; F ig. 2 is a detail view of the fabric on an enlarged scale.

The fabric, which is intended to be manufactured on the ordinarytraverse warp Inachine, is composed of three sets of threads, twofilling warp threads and one binding warp thread. The two sets of fillerthreads are marked respectively a, a, a2, etc. and ZJ, 5', b2, While thebinder threads are marked @650,0 etc.

It will be observedthat the linished fabric, generally speaking,comprises longitudinal bars a, fr', m2, m, etc.,4 of interlooped threadscomposed of all three sets of threads, and transverse bars y, y', y2, y,etc. of iioating threads composed'of the two sets of filler warps. Morespecifically it-will be observed that the iiller thread a (starting,-say from point m) extends transversely in one direction to thelongitudinal bar thence' directly forward between adjacent intersectionsof thevlongitudinal bar m and the transverse bars y and y', thencetransversely in the opposite direction to the adjacent longitudinal barthence is formed into a loop at the intersection of longitudinal bar wand transverse bar y', thence extends forward, in the course of which itis reversely curved upon itself, to the intersection of bars m" and'l2/2, and thence transversely toward longitudinal bar :v Following theller thread b from the same point m, it will be observed that it extendstransversely in one direction to the longitudinal'bar m, thence isformed into a .loop at the intersection of longitudinalbar andtransverse' bar y, thence extends forward, in the course of which it isreversely Acurved upon itself, to' the intersection. of bars and y,thence transversely in the opposite direction to the longitudinal barw', thence directly forward .between adjacent intersections of thelongitudinal bar and the transverse bars y and y2, andthence'transversely toward Llongitudinal bar i Following the binderthread c from the point n,-the same extends forward through the rloop ofthe thread 6, at the intersection of bars,v m and y, thence forwardunder thread and thread. @,thence through one pocketof the reverselycurved portion vof thread b', thence back over the neck of said loop ofthreadb, thence forward successively over thread andnder Ithread a andthrough the loop of thread a at the intersection of bars and '3`/,thence back successively over and'under thread b and through the otherpocket of the reversely through said loop of thread a, thencefor-Acurved portion'of thread b, thence again ward under threads o andthence through one pocket ofthe reversely curved portion ofA thread a,thence back overfthe neck'of 'saidioop of thread a, .thence for.

versely curved portion of thread a.

From the foregoing description it will be understood that the threadsare so looped together thati'eif any one thread should be broken or cutat alny point, any attempt, by pulling the loose fend,- to unravel thefabric, would result in" tying a knot or knots in the threads and thuseven more securely securing the several threads together.

Having now fully. described my invention, what I claim and desire toprotect by Letters Patent is:

1. A knitted fabric composed of iiller warp threads each extendingsupcessively transversely and forwardly, throughout the length of thefabric, each of said threads, in its alternate forward extensions, beingsuccessively formed into a loop and reversely curved, and a binder warpthread extending through and around the necks of the vand throughtheother pocket of the re-4 noso, reo

loops, and through the pockets of said re- Versely curved portions, ofthe filler Warp threads, substantially as described.

knitted fabric composed of two sets of filler Warp threads and a set ot'binder Warp threads, said filler warp threads eX- tending successivelytransversely and forwardly and each Eller warp thread, in its alternateJforward extension, being sucsessively looped and reversely curved",ealch binder warp thread extending through and around the 11er-hs of theloops, and through tbe pockets of said re-.versely Curved pcrtions, ofthe filler warpfthreads, and in so extending forming loops bindingtogether adjacent loops vand pockets formed by the filler Warp threads.

3. A knitted fabric efmiposed of longitudinal chains composed ot' a setof bindingv Warp threads and two sets of iller Warp threads, andtransverse bars composed of said two set-s of iller Warp threads, eachof said filler Warp threads being looped and reversely curved in theformation of said chain, and each of said binder warps extending,` alongone chain only and in so eX- tending passing through the loops, and thepockets of the reversely curved portion, .of thef'izller Warp threads,and binding together the loops and pockets of the same, and also theloops and pockets of dil'lerent filler and Warp threads, substantiallyas described.

In testimony of which invention, I have hereunto set my hand, atPhiladelphia, on this 11th day of March, 1912.
